I noticed some problems with the RME drivers yesterday (4.0.82), where totalmix seemed to be registering itself with the system as a microphone repeatedly and maybe failing? This was coinciding with audio dropouts and glitches.

Has anybody seen this before?
[Babyface Pro]
Never seen before.
Bitwig and Totalmix are fighting each other for the Microphone lady ?
MacOS can't handle this.
i did a test and both apps are working with no issue.
Ventura 13.4 update today
RME driver 408 with the Digiface USB
BitwigStudio 4.4
Thanks for checking! I'm on 13.3.1 so I guess I'll play the update game.
No such luck unfortunately. Is there an official RME support channel for this kind of thing? I very much doubt that this is Bitwig related, it looks like this is between the driver and the OS.
Not something I've seen... When exactly does this happen? Only with Bitwig running?
It's hard to say because I pretty much always use Bitwig and my RME devices at the same time.
I can try and a) use my UCXII for non music-related things and see how it goes b) shut down Bitwig next time it's happening and see if it stops.
It's a little strange because sometimes I can get it to stop by opening Totalmix and recalling a different snapshot or jiggling something (but not always so not very conclusive).
Any suggestions on getting more information?
Although, you know what, on careful watching of the video, it's actually Bitwig that's registering and unregistering and not Totalmix. I'll ping them as well!
IIRC it was Totalmix that was flapping if I go down to the microphone section, but I'll get more evidence of that before I say more.

I would compare with another DAW product which is major player / de facto standard in the DAW market since long:
- Reaper is easy to install and has good quality or
- demo version of Cubase
Haven't been able to reproduce with Reaper yet, but that's not conclusive since I don't have much in the way of large projects there and I'm not using it as frequently. However, I did manage to capture a video of the problem where it's Totalmix that's flapping.

This did stop once I shut down Bitwig, but that doesn't really prove anything one way or the other. I'm unable to reproduce this at all using internal audio, which points away from BW and towards the RME drivers.
[Talking to BW and Apple support as well]
In the Mac system preferences : security & privacy - Microphone
Check if Totalmix and Bitwig are enabled for access.
They are both enabled. I tried all the permutations of [have microphone access, no microphone access] X [Bitwig, TotalMix] and none of the ones that were usable solved the problem.
So I talked to Bitwig support, and their thinking is that because it doesn't happen with internal audio on the MacBook it is not happening inside the Bitwig audio engine and is somewhere between coreaudio and the RME driver.
Can somebody from RME comment on how I might go about getting more information? I'm happy to do anything I can to help track this down.
If anybody else feels like having a go at testing this, I've noticed that it's a lot easier to reproduce at high buffer sizes - I've been running at 2048.
You could simply set up some random projects in Reaper and keep enabling effects and plugins... Doesn't have to make any musical sense.
I'll do that if I get some time. However, at this point I'm pretty comfortable saying it's an RME driver issue because:
- Have spent hundreds of hours using the internal audio (when I'm not near one of my RME devices) in the same situation without issue, whereas I've spent about 1 hour trying to reproduce unsuccessfully with Reaper.
- It's noticeably worse with the 4.08 driver than with the 3.28 driver.
I've emailed support officially (which might be you anyway?) - I'd forgotten there even was a support email for RME 
Ok, that was easy enough:
Are BF Pro and UCX II both used? Above you mention BF Pro, but in the video TM FX is not connected to the BF Pro. To further find the cause you should use only one interface and restart TM FX so that in the device list only the current one is shown.
Then for a further test disable the mic inputs of the interface and only use the other channels in a project.
